Want this question answered?
Radio and light waves are electromagnetic waves, sound waves are not.
Radio signals travel at (essentially) the speed of light, as they are electromagnetic waves like light. Sound waves travel at roughly 1200 km/h. Now you have enough information to answer your own question.
When you listen to the radio, you are hearing sound, which has no resemblance to light, radio waves, or x-rays. However, the sounds you hear are created in the radio receiver, using information that was carried to your location by means of radio waves.
From highest to lowest: Gamma, X-ray, Infrared (heat), Visible (Red, Yellow, Green, Blue), Ultraviolet, Radio. Radio waves are not sound waves but are the light rays that sound is converted into before being sent to your radio and your radio converts these light rays back into sound.
Sound.
Light is an electromagnetic wave; and those are transverse. Sound is usually a longitudinal wave.
Sound.
Radio signals propagate faster than sound signals. Speed of light (radio) is about 186,000 mps Speed of sound is about 1100 fps (0.5 mps).
Radio waves are sound. Therefore, yes, by definition, they travel at the speed of sound.
They both travel fastly
